I'm getting some trouble with the function T_CONFIG.

I'm tryint to use this fb to change dinamically the ip address of my 1214C cpu.

I've followed the instruction found on the tia portal guide and on the 1200 system manual. So i've enable the option"Set IP address using a different method" in the hardware config and add the fb on the OB1 with all its correct parameter.

When i try to active the request, nothing seems appening. The output done,busy, error are always false. Also the status is always with 00700000 value and Err_Loc is always 0

Seems like no request is active, even if the input is enabled.

What i'm doing wrong?

Thanks
